- CHANNEL FOR. AUTOMOBILE WINDOWS AND WINDSHIELDS.

Application filed January 8,- 1927. Serial No. 159,756.

My invention relates to channels for automobi e windows and Wind shields, and more particularly to an article of this kind in which a fabricated strip is utilized as a pro- 6 tecting cushioning medium between the light of glass and the metal troughed portion of the channel so as to affordan effective protection for the glass and minimize likelihood of its breakage from the various shocks and 10 jars to which glass about an automobile is subjected.

A channel embodying the invention includes therein a fabricated strip, the construction of which is such as to ensure an exact conformation of this strip with the glass, and with the troughed metal part of the channel, irrespective of slight surface irregularities in the glassor in'said troughed portion, not only by reason of the resiliency inherent to the material of said strip, but because of the inclusion in the strip of strata having relatively different degrees. of resiliency so as to permit not only the adjustment of opposite strata of the strip to irregularities in the part with which they contact, but to permit a bodily displacementof the stratum having the lower degree of resiliency-When its adjustment to the surface with which it contacts requires a yielding of the material of this stratum in excess of its limit of resiliency.

The strip of fabricated material is so formed as to possess throughout waterproof properties which prevent deterioration by reason of the exposure of the strip to theelements. Y

The fabricated strip includes therein one surface stratum composed of composition cork and a second stratum of unvulcanized rubber, both of which strata b reason of their lack of tensile strength are rmly bonded to, what may be termed, a vcorefof a textile fabric possessing a degree of resiliency sufficiently low to avoid stretch or attenuation of the strip in its entirety, but flexibility suflicient to permit distortion when the conditions of use require. v

The inventionconsists primarily in a channel for automobile windows and wind shields embodying therein a troughed metal portion and a linin therefor com osed of a fabricated strip iaving a texti e core, a surface stratum of waterproof resilient 7 material bonded to one side thereof, and a surface trough a.

stratum of material having a relatively.

higher degree of resiliency than said other stratum bonded to the other side thereof; and in such other novel characteristics as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended. I

Fig. 3 is a view of a portion of the resilient fabricated strip. Like letters refer to like parts throughout the several views.

In the embodiment of the invention shown in the drawings, the dimensions of the resilient strip are greatly exaggerated with relation to the thickness of the glass, as are .the dimensions of the metallic trough itself, since in actual practice the fabricated strip will have a thickness of approximately only three thirty-seconds ofan inch.

In the drawings, a portion of the usual metal trough a of an automobile window or wind shield. is indicated, and b is the light of glass supported thereby. Within the trough a is a strip of fabricated material folded about the edge of the glass 6, and if desired cemented thereto. This strip consists of a non-elastic core 0 of a suitable textile such as thin cotton duck, having upon one side thereof a thin facing stratum d of composition cork, which composition cork consists of granularcork, the separate granules of which are firmly united by a suitable resilient binder or adhesive which may e unvulcanized rubber, ozivother binders coriimonly 'used in the productionof composition cork; and upon the other side thereof, a thin facing strip e .of highly resilient material such as rubber, preferably unvulcanized rubber bein used. In fact, as to the rubber facing, the textile core may be merely heavily frictioned. By using unvulcanized rub- L her for the facing stratum e, I not only secure,a relatively higher degree of resilience in this facing than in the facing d, but secure a surface which will readily conform with and adhere'to the wall of the metal In the stratum d, I may employ cork granules formed from low grade cork and of dimensions sufliciently small to make this glass or in the stratum 03 will be compensated for in part by compression of, and. in part by physical displacement of portions of the sur- 1 sirable in actual practice as it ensures not. only a tight fit with the glass 6, but facilityface d and of the core 0, and by localized compression of the surface 0.

The exposed face of the composition cork stratum (Z has a pebbled elfect, due to the fact that after the composition has been rolled upon the core 0, there will be irregular expansion of some of the cork granules when the pressure from this roller is relieved. This roughened surface has been found highly dein applying the strip to the glass and to the trough a. Y c

In the production of the material from which the strips are cut, the composition cork facing stratum d is firmly bonded to the fabric core a, the binding medium relied upon beingeither that which is incorporated in the composition cork, or an ordinary adhe- S1Ve or binder applied to the fabric core a.

If desired, lampblack or other colored pigment may be admixed with the cork c0mp0sition, but this is merely a matter of finish and is not essential to the invention. To give a little better finish to the stratum d, this surfage may be given a coating of shellac, this however being also optional. 7

In applying the strip to the glass 6 and to the trough a it is the ordinary practice to cement the stratum d to the glass 1), and the stratuin e to thg trough a. This practice is preferable, but is not essential to the invention. v

The essentials of the invention are the employment in a channel for automobile win dows and wind shields of a metallic trough for a l ght of glass supported from this trough, and a cushioning strip between the said trough and said liglhfllilfi glass, aid if ,w c strip as a desired, cemented to bot surface stratum of composition cork or other equivalent resilient material engaging the glass and bonded to a textile fabric core having bonded thereto upon its other face a with the metallic trough.

stratum of unvulcanized rubber contacting As heretofore stated, the dimensions shown in the drawings are rossly exaggerated and much enlarged in order to clearly distinguish the cgnstituent parts of the strip. Ordinarily the strip of cushioning material will range from three to five thirty-seconds of an inch, the fabric being very light stock. The composition cork stratum d is relatively thicker than the rubber stratum'e, and both of these arerelatively thicker than the fabric.

It is therefore not my intention to limit the invention to the proportions shown in the drawings.

Having described the invention, what I claim as new and desire to have protected by Letters Patent,-is

- 1. A channel for automobile windows and higher degree of resiliency than said other stratum bonded to the other side thereof.

w 2. A channel for automobile windows and A wind shields embodying therein a troughed metal portion and a lining therefor composed ;of a fabricated strip having a textile core, a

surface stratum of cork granules bonded to-' gether and to one side thereof, and a surface stratum of soft rubber bonded to the other side thereof. v

3. A channel for automobile windows and wind shields embodying therein a troughed metal portion and a linin therefor composed of a fabricated strip having a textile core, a surface stratum of cork granules bonded together and to one side thereof, and a surface stratum of unyulcanized rubber bonded to the other side thereof.

In witness whereof I have hereunto aflixed my signature, this 3dday. of January, 1927 CHARLES E. MQMANUS.
